------- Additional Comments From tor.andersson at artifex.com  2009-07-29 07:57 -------
Our interpolation of images on the edge is wrong. We interpolate the edges as if the outside of the image 
was transparent instead of clamping to the edge colors. We're also off by half a texel since the 
interpolation only occurs towards one side in these examples where the images are 1x1 in size. The bug 
was not as apparent before the patch that removed an "optimization" where these 1x1 images were 
replaced by solid rectangle fills. That optimization didn't work for 1x1 images with transparency.
